Follow this guide if you prefer Debian Jessie.
It depends on the number and type of virtual machines. For common scenarios are server memory, storage and network bandwidth the most critical requirements.
RAM is the main issue. Multiply the number of concurrent workstations by the amount of memory each one requires and that is the total RAM the server must have.
The faster the disks, the better. Ravada uses incremental files for the disks images, so clones won’t require many space.
Follow this guide if you are only upgrading Ravada from a previous version already installed.
We only provide support for Ubuntu 18.04 LTS (bionic).
We provide deb Ubuntu packages. Download it from the UPC ETSETB repository.
Install libmojolicious-plugin-renderfile-perl package:
sudo apt-get install libmojolicious-plugin-renderfile-perl
Then install the ravada package, it will show some errors, it is ok, keep reading.
wget http://infoteleco.upc.edu/img/debian/ravada_0.3.1_all.deb sudo dpkg -i ravada_0.3.1_all.deb
The last command will show a warning about missing dependencies. Install them running:
sudo apt-get update sudo apt-get -f install
MySql required minimum version 5.6
It is required a MySQL server, it can be installed in another host or in the same one as the ravada package.
sudo apt-get install mysql-server
After completion of mysql installation, run command:
MySQL database and user¶
It is required a database for internal use. In this examples we call it ravada. We also need an user and a password to connect to the database. It is customary to call it rvd_user. In this stage the system wants you to set a password for the sql connection.
When installing MySQL you wont be asked for a password, you can set a password for the root user in MySQL via mysql_secure_installation or type your user’s password when it ask’s you for a password.
Create the database:
sudo mysqladmin -u root -p create ravada
Grant all permissions on this database to the rvd_user:
sudo mysql -u root -p ravada -e "grant all on ravada.* to rvd_user@'localhost' identified by 'changeme'"
Create a config file at /etc/ravada.conf with the username and password you just declared at the previous step. Please note that you need to edit the user and password via an editor. Here, we present Vi as an example.
sudo vi /etc/ravada.conf db: user: rvd_user password: changeme
Ravada web user¶
Add a new user for the ravada web. Use rvd_back to create it. It will perform some initialization duties in the database the very first time this script is executed.
When asked if this user is admin answer yes.
sudo /usr/sbin/rvd_back --add-user user.name
The client must have a spice viewer such as virt-viewer. There is a package for linux and it can also be downloaded for windows.
